Anwar and his son were arrested on August 15 in connection to a case related to money laundering through fake bank accounts.

Moreover, the FIA is investigating 32 people in relation to money laundering from fictitious accounts, including Asif Zardari and his sister Faryal Talpur. Zardari’s close aide Hussain Lawai was arrested last month in connection with the probe.

Earlier, over 20 'fake' accounts at some private banks were opened in 2013, 2014 and 2015 from where transactions worth billions of rupees were made. The amount, according to FIA sources, is said to be black money gathered from various kickbacks, commissions and bribes.
